Good day Larry,
You asked about the Clem engine drawings, I have looked everywhere but can
not find it in my files. I thought that I obtained the information from
Jim's page so looked it up and also checked the Sumeria and Solaris files
and found nothing.
The keely archives are still not available and am sure that it where I got
the information from. However to keep you in the picture, the following:
The story appeared as a second hand account of someone speaking to someone
else who also gave a rough drawing of how he thought it worked.
There was also a mention that the prototype is supposed to be still running
under concrete, why they would want to bury it is beyond me. They did not
enlighthen us as to where the thing was buried.
The rough drawing shows a cone with 8 nozzles and pressurised from the
narrow end.The nozzle feeds are pipes spiralled over the cone a la Victor
Schaubergers device. A pump is pressurising the cooking oil which upon it's
return goes to a heat exchanger before it enters the pump again.
On the wide end it shows a power take off and a starter motor.
When I looked at it ( I know a fair bit about hydraulics) I immediately
thought the interpretation to be wrong.
There was no connection between the pump and the power take off and if it
was to be self sustaining, the pump would have to be driven by the cone.
At say 3000 R.P.M., The nozzles travel at 84 kilometres per hour.
For this to be driven by oil pressure, needs a reaction speed of 168
kilometres per hour and give you the task of telling me what pressure and
what nozzle size is required to do this. My off the cuff guess is a minimum
of 600 p.s.i which in itself takes a fair horsepower to achieve.
Hydraulic pumps are positive pumps without slippage and heat up very
quickly and at the same time can become motors if fed oil in reverse.
If the heat differential is the driving force, this would almost certainly
mean that at a certain point, the suction from the nozzles will overcome
the need to use the pump so why use the pump in the first place !.(does
the pump become the motor ????
The starter motor would create the suction and depending on cavitation
problems,(water does not allow you to go over 27 inches mercury before it
cavitates and I am not aware of this problem in hydraulic oil) the oil
would still heat up from the friction in the pipes.
Unless the pump is driven by electricity in the normal way and a generator
hooked up to the power take off giving excess power I am not aware how or
what sort of energy was taken off.
So that is how far I got but for to say that it is an extremely curious
account of something that appeared and disappeared. We have a lot of
bitumen plants in this country and I have never seen anything that could
remotely look like the description, nor have I heard of bitumen pumps
running on. However, I am willing to give it a try as it is relatvely
simple to make. The pressure can be applied without excessive sealing
problems because the whole thing is encased in a 44 gallon drum so leakeage
should not worry too much as long as the pump has plenty of reserve
capacity. Also I would not use cooking oil. I would use Mobil No 1, a
synthetic oil that does not carbonise. The bearings are cheap to obtain
because 3000 R.P.M. is not excessive.
I hope this helps and also could be made in miniature because the effects
should be the same providing you get the right velocities at the nozzle to
heat the oil.
Have fun with this and if I get to it will let the group know how I got on.
